[QGIS-Developer] PyQGIS: how to retrieve symbolLayers in renderPass order

[Tom Chadwin]

In the absence of such a method, I'm doing this:

symbolLayers = {}
for i in xrange(symbol.symbolLayerCount()):
    sl = symbol.symbolLayer(i)
    if renderer.usingSymbolLevels():
        k = sl.renderingPass()
    else:
        k = i
    symbolLayers[k] = sl
stackedSLs = sorted(symbolLayers.iterkeys())

I think it works:

If anyone has a better method, do let me know.
    
Thanks

Tom
